Cai Tong took all the drawings and laid them out one by one, and if the table was not enough, he and Gu Yicheng and others held them with their hands so that Zhou Ziyan could see them.

The phantom screen is a three-dimensional display, and what is even more exaggerated is that every door of the fortress, every edge and corner is done according to the drawings, not to mention the doors in various positions of the internal passage windows, even the internal dome structure and the window shapes of different doors, and the number of steps of the stairs that surprised everyone was not more than one layer and no less than one layer.

If these are the drawings with lines, those who have entered the fortress have not been able to remember much, and they can't see it from the blueprints, but Zhou Ziyan has done all of them, and even the electric control board under the hidden wall is not falling.

"This ...... Is this all what you can see on the drawings? Cai Tong's assistant couldn't close his mouth in shock.

Cai Tong also exclaimed with a face: "It's amazing, many of them have only marked abbreviated symbols, but I didn't expect Miss Zhou to be able to make sketch models, Miss Zhou is the most powerful modeler I have ever seen." ”

Zhang Zhen looked at it and was not shocked to drop his jaw, he felt powerful when he created a chariot before, but the first floor of this fortress is many times more complicated than the chariot, he has entered the upper layers, and even carefully swept it with glasses, and now he only has a general impression, and Zhou Ziyan has never entered, and it is impossible to see it at her age, she can actually model it with a drawing with only abbreviated symbols, and it is exactly the same, there is no difference in small details, this is really amazing.

Zhou Ziyan didn't seem to hear everyone's discussion at all, her eyes swept the drawings and her hands were like a pair of phantom hands, and like the hands of God, creating models on the phantom screen quickly and beautifully, layer after layer, time was lost little by little in everyone's amazement and intent.

The speed of copying more than three layers is relatively fast, and when it is below three layers, because only Cai Tong's rough speculation, Zhou Ziyan's speed slows down.

Others can only see that Zhou Ziyan sometimes hesitates for a while, and the speed of creation is slower, but Cai Tong sees more, his blueprint has many flaws that are being corrected, and those areas and structural locations that cannot be determined and can only be temporarily speculated, Zhou Ziyan has made a more accurate drawing.

I didn't realize that the night was already deep, but I didn't realize that so much time had been lost, and I was watching intently.

"Whew." Zhou Ziyan exhaled, rubbed her sour wrist and said: "More data is needed below the third layer, and now we can only briefly speculate on the modeling, and if the blueprint is correct above the third layer, there should be no problem." ”

"Awesome!" Cai Tong put down the blueprint in his hand and applauded excitedly.

Everyone was busy and applauded enthusiastically.

Zhang Zhen also clapped his hands and walked to the phantom screen, he clicked open a door of the four-story infantry combat platform with his hand, a long space inside, and the armor on the wall was pulled out and put down, revealing a row of external battle portholes, without entering the fortress, he already felt what the fourth layer of the fortress was like.

Zhou Ziyan couldn't help but feel a little shy when she saw that everyone was applauding and appreciating herself, "The preliminary modeling is not difficult, with the support of Cai Hufa's data, more data is needed below the fourth layer for calculation and speculation." ”

"Don't be modest, you've done something that is difficult for others to do, it's not early today, rest first, and talk about it tomorrow." Zhang Zhen yawned, and finally felt sleepy after reading the wonderful modeling.

Sun Rong hurriedly said: "Then the city lord will rest first, the cleaning of the fortress will be non-stop day and night, and tomorrow the city lord can enter the fortress to take a look for himself." ”

Zhang Zhen nodded and walked out with Zhou Ziyan and Sakura.

Xiao Yunfei followed from outside the tent, now there is no need for Gu Yicheng to be responsible for the safety of Zhang Zhen in the camp, Xiao Yunfei had already ordered people to distribute the chariots around Jiaolong to prepare for the defense when camping.

"Zi Yan, let Sakura accompany you into Captain Xiao's command car to rest, Jiaolong's carriage is full of goods and can't rest." Zhang Zhen was about to open the Jiaolong carriage and let Zhou Ziyan in, only to remember that it was full of goods.

Zhou Ziyan was excited to enter Jiaolong, and she was a little lost, but when the goods came, she could only take a nap on the chair in front of her, so she could only turn around and enter the command car on the side.

Zhang Zhen lit a cigarette and gave Xiao Yunfei a cigarette and said, "It's all normal after you come over, right?" ”

Xiao Yunfei nodded and said: "The Gopher Gang looks normal, and the digging work is also very hard, the material collection on the fourth floor called me to supervise, and the weapons and some materials collected have been temporarily sealed." ”

"Okay, this time Zhou Ziyan and Sakura will stay here, you protect them." After Zhang Zhen finished speaking, he entered the Jiaolong cab to rest.

Xiao Yunfei was busy, he was shocked when he came here to see the fortress, looking at the fortress getting deeper and deeper, the weapons that came out of it, the structure inside the fortress, Xiao Yunfei was excited, he didn't expect that it was really the legendary Hongcheng land fortress, which can be called the strongest war weapon on land in the last days.

And this land fortress has been bought by Zhang Zhen, if this land fortress is repaired, the combat power of the wasteland is comparable to a small force, and it is not impossible to compete with a force like the Four Seas Kingdom.

However, no one will know the real reason why Zhang Zhen bought the land fortress, they will not know how terrible the combat power of the land fortress will be after the evolution of the chariot, and it is not impossible to increase the combat power of the land fortress by ten times.

Cleaned up almost, Jiaolong can detect more, Zhang Zhen asked Chariot Ji to calculate, the evolution of the current form of the land fortress alone may require 70 million energy, and because most of the components are damaged, if it is fully repaired, it may also cost hundreds of millions, and the chariot suicide Zombie Queen is only 30 million, which is far from enough.

This evolution can be said to be jumping, Jiaolong is now a silver star, this evolution will inevitably be a gold level, considering the many rare technologies contained in the fortress, it is the most appropriate way to deal with it after repairing and then evolving, otherwise many technologies will disappear because the vehicle itself is not of high technology level and cannot be repaired, and after repair, the vehicle will be able to absorb technology, so that there will be no loss.

In addition to helping to dig the buni, Zhou Ziyan's more important role is to lead the repair of the fortress, and the marriage with Yu Lihuang must be able to solve some of the maintenance materials, and if it is not enough, find a way to do it from reality or other forces, no matter what, it must be repaired.

It is very problematic to solve the funding gap at the moment, and it is expected that the Four Seas Kingdom and the Black Gold Group will still have to make a deal before turning their faces, and they will not exchange materials for them, but will only give crystal coins, and those people think that it is useless for him to have crystal coins, because it is impossible for him to buy weapons and chariots.

Buying a fortress and repairing a fortress plus evolution, conservatively estimated to cost more than 200 million crystal coins, which is also an astronomical amount, relying on these two forces to estimate that 100 million into the account is already the limit, which is far from enough.

If the core of the Corpse King is sold, the Four Seas Kingdom and the Black Gold Group will also rush to ask for it, but this thing is too scarce, the power system of the fortress has not yet been detected, if it is damaged or backward, then the crystal core furnace will become the only way to make the fortress work, and the power system of the dragon cannot drive these hundreds of tons of guys.

Zhang Zhen pondered, there are so many problems to face, but he likes challenges, and now he is not used to too mediocre days.
